53-485: Teppanyaki ( 鉄板焼き , teppan-yaki ) , often called hibachi ( 火鉢 , "fire bowl") in the United States and Canada, is a post-World War II style of Japanese cuisine that uses an iron griddle to cook food. The word teppanyaki is derived from teppan ( 鉄板 ), the metal plate on which it is cooked, and yaki ( 焼き ), which means grilled, broiled, or pan-fried. In Japan, teppanyaki refers to dishes cooked using
106-413: A charcoal pile or clamp . This was essentially a pile of wooden logs (e.g. seasoned oak) leaning in a circle against a chimney. The chimney consisted of 4 wooden stakes held up by some rope. In the clamp too the logs were completely covered with soil and straw allowing no air to enter. It must be lit by introducing some burning fuel into the chimney. The logs burned slowly and transformed into charcoal over
159-464: A wood gas generator . In 1931, Tang Zhongming developed an automobile powered by charcoal, and these cars were popular in China until the 1950s, and in occupied France during World War II , where they were called gazogènes . Charcoal is used in the production of black powder , which is used extensively in the production of fireworks. It is usually ground into a fine powder, with air float grade being
212-435: A deep brown-black after some time at 280 °C (540 °F), and an easily powdered mass at 310 °C (590 °F). Charcoal made at 300 °C (570 °F) is brown, soft and friable, and readily inflames at 380 °C (720 °F); made at higher temperatures it is hard and brittle, and does not fire until heated to about 700 °C (1,300 °F). Modern methods employ retorting technology, in which process heat
265-400: A filter, catalyst , or adsorbent. Charcoal burns at temperatures exceeding 1,100 degrees Celsius (2,010 degrees Fahrenheit). By comparison, the melting point of iron is approximately 1,200 to 1,550 °C (2,190 to 2,820 °F). Due to its porosity, it is sensitive to the flow of air and the heat generated can be moderated by controlling the air flow to the fire. For this reason charcoal
318-456: A filter. Activated charcoal readily adsorbs a wide range of organic compounds dissolved or suspended in gases and liquids. In certain industrial processes, such as the purification of sucrose from cane sugar, impurities cause an undesirable color, which can be removed with activated charcoal. It is also used to absorb odors and toxins in gaseous solutions, as in home air purifiers and some types of gas mask . The medical use of activated charcoal
371-576: A flaming onion volcano. Another piece of equipment in the same family is a flattop grill , consisting of a flat piece of steel over circular burners and typically smaller and round, like a Mongolian barbecue . Typical ingredients used for Western-style teppanyaki are beef, shrimp, scallops, lobster, chicken and assorted vegetables. Soybean oil is typically used to cook the ingredients. Japanese-style teppanyaki may also use noodles ( yakisoba ) or cabbage with sliced meat or seafood ( okonomiyaki ), which are cooked using vegetable oil, animal fat, or
424-503: A large range of purposes including art and medicine, but by far its most important use has been as a metallurgical fuel. Charcoal is the traditional fuel of a blacksmith's forge and other applications where an intense heat is required. Charcoal was also used historically as a source of black pigment by grinding it up. In this form charcoal was important to early chemists and was a constituent of formulas for mixtures such as black powder . Due to its high surface area , charcoal can be used as
477-414: A microscopic scale. Charcoal may be used as a source of carbon in chemical reactions. One example of this is the production of carbon disulphide through the reaction of sulfur vapors with hot charcoal. In that case, the wood should be charred at high temperature to reduce the residual amounts of hydrogen and oxygen that lead to side reactions. Charcoal may be activated to increase its effectiveness as
530-457: A mixture. In Japan, many teppanyaki restaurants feature Kobe beef or Wagyu beef. Side dishes of mung bean sprouts , zucchini (courgettes) (though this is not a popular vegetable in Japan and rarely found in that market), garlic chips (crisps), or fried rice usually accompany the meal. Some restaurants provide sauces in which to dip the food. In Japan, only soy sauce is typically offered. In
583-425: A period of 5 days. If the soil covering became torn or cracked by the fire, additional soil was placed on the cracks. Once the burn was complete, the chimney was plugged to prevent air from entering. The true art of this production method was in managing the sufficient generation of heat, by combusting part of the wood material, and the transfer of the heat to the wood in the process of being carbonized. The operation

It is also utilized in cosmetics, horticulture, animal husbandry, medicine, and environmental sustainability efforts, such as carbon sequestration. However, the production and utilization of charcoal can have adverse environmental impacts, including deforestation and emissions. Illegal and unregulated charcoal production, particularly in regions like South America and Africa, poses significant challenges to environmental conservation efforts. The production of wood charcoal in locations where there
689-460: A regulated charcoal industry that required replanting and sustainable use of the forests "would give their people clean efficient energy – and their energy industries a strong competitive advantage". Recent assessments of charcoal imported to Europe have shown that many charcoal products are produced from tropical wood, often of undeclared origin. In an analysis of barbecue charcoal marketed in Germany,
742-655: A short time, research on Terra preta soils in Amazonia has discovered the widespread use of biochar by pre-Columbian natives to ameliorate unproductive soil into soil rich in carbon . The technique may find modern application, both to improve soils and as a means of carbon sequestration . Charcoal is mixed with feed, added to litter , or used in the treatment of manure . Poultry benefits from using charcoal in this manner. A concern that activated charcoal might be used unscrupulously to allow livestock to tolerate low quality feed contaminated with aflatoxins resulted in

The chef might juggle utensils, flip a shrimp tail into their shirt pocket, catch an egg in their hat, toss an egg up in the air and split it with a spatula, or flip flattened shrimp pieces into diners' mouths. Hibachi The hibachi ( Japanese : 火鉢 , fire bowl) is a traditional Japanese heating device. It
848-586: A smelting fuel has been experiencing a resurgence in South America resulting in severe environmental, social and medical problems. Charcoal production at a sub-industrial level is one of the causes of deforestation. Charcoal production is now usually illegal and nearly always unregulated, as in Brazil , where charcoal production is a large illegal industry for making pig iron . Massive forest destruction has been documented in areas such as Virunga National Park in
901-613: A steady supply of wood for charcoal production. The scarcity of easily accessible wood resources eventually led to the transition to fossil fuel equivalents like coal. Modern methods of charcoal production involve carbonizing wood in retorts, yielding higher efficiencies compared to traditional kilning methods. The properties of charcoal depend on factors such as the material charred and the temperature of carbonization. Charcoal finds diverse applications, including metallurgical fuel in iron and steel production, industrial fuel, cooking and heating fuel, reducing agent in chemical processes, and as
954-475: A teppan, including steak, shrimp, okonomiyaki , yakisoba , and monjayaki . Teppan are typically propane-heated, flat-surfaced, and are widely used to cook food in front of guests at restaurants. They are commonly confused with the hibachi barbecue grill , which is called shichirin in Japanese, and has a charcoal or gas flame and is made with an open grate design. With a solid griddle-type cook surface,
1007-426: A way to improve the health of people burning raw biomass for cooking and/or heating. Modern "charcoal" briquettes, widely used for outdoor cooking, are made with charcoal but may also include coal as an energy source as well as accelerants, binders and filler. To contain the charcoal and use it for cooking purposes, a barbecue grill may be used. A small Japanese charcoal grill is known as a shichirin . A brazier
1060-476: Is a brazier which is a round, cylindrical, or box-shaped, open-topped container, made from or lined with a heatproof material and designed to hold burning charcoal . It is believed hibachi date back to the Heian period (794 to 1185). It is filled with incombustible ash , and charcoal sits in the center of the ash. To handle the charcoal, a pair of metal chopsticks called hibashi ( 火箸 , fire chopsticks)

#17330862074451166-587: Is a container used to burn charcoal or other solid fuel. To start the charcoal burning is harder than starting a wood fire and charcoal lighter fluid may be employed. A chimney starter or electric charcoal starter are tools to help with starting to light charcoal. Approximately 75% of fuel burned in Haiti is charcoal. Certain types of charcoal, such as wood charcoal, are used for reducing heated metallic oxides to their respective metals: Charcoal can also be used to reduce super heated steam to hydrogen (along with
1219-474: Is an abundance of wood dates back to ancient times. It generally began with piling billets of wood on their ends to form a conical pile. Openings were left at the bottom to admit air , with a central shaft serving as a flue . The whole pile was covered with turf or moistened clay . The firing began at the bottom of the flue, and the fire gradually spread outward and upward. The traditional method in Britain used
1272-485: Is generally more effective as an adsorption filter due to its increased porosity and surface area. Charcoal is used for drawing , making rough sketches in painting , and is one of the possible media used for making a parsemage . It usually must be preserved by the application of a fixative . Artists generally utilize charcoal in four forms: One additional use of charcoal was rediscovered recently for horticulture . Although American gardeners have used charcoal for

For example, it is often used to reduce discomfort and embarrassment due to excessive gas ( flatulence ) in the digestive tract. Animal charcoal or bone black is the carbonaceous residue obtained by the dry distillation of bones. It contains only about 10% carbon,
1378-513: Is necessary to avoid accidents. Hibachi must never be used in airtight rooms such as those in Western buildings. In North America , the term hibachi refers to a small cooking stove heated by charcoal (called a shichirin in Japanese), or to an iron hot plate (called a teppan in Japanese) used in teppanyaki restaurants. This article related to the culture of Japan
1431-601: Is no evidence to determine its safety and effectiveness. Red colobus monkeys in Africa have been observed eating charcoal for self-medication. Because their leafy diets contain high levels of cyanide , which may lead to indigestion, they learned to consume charcoal, which absorbs the cyanide and relieves discomfort. This knowledge is transmitted from mother to infant. Production and utilization of charcoal, like any use of woody biomass as fuel, typically results in emissions and can contribute to deforestation. The use of charcoal as
1484-421: Is recovered from, and solely provided by, the combustion of gas released during carbonization. Yields of retorting are considerably higher than those of kilning, and may reach 35%-40%. The properties of the charcoal produced depend on the material charred. The charring temperature is also important. Charcoal contains varying amounts of hydrogen and oxygen as well as ash and other impurities that, together with
1537-478: Is still widely used by blacksmiths. Charcoal has been used for the production of iron and steel (where it also provided the necessary carbon) since at least 2000 BCE , with artifacts having been found in Proto-Hittite layers at Kaman-Kalehöyük . Charcoal briquettes can burn up to approximately 1,260 °C (2,300 °F) with a forced air blower forge. In the 16th century, England had to pass laws to prevent
1590-440: Is used to obtain showers of golden sparks in pyrotechnic compositions. Charcoal is also incorporated in multiple cosmetic products. It can be produced from regular bamboo cut into small pieces and boiled in water to remove soluble compounds. Raw bamboo charcoal is obtained after drying and carbonization in an oven at elevated temperature. The role of charcoal in cosmetics is based on its highly effective absorbing properties at
1643-612: Is used, in a way similar to Western fire irons or tongs . Hibachi were used for heating, not for cooking. It heats by radiation , and is too weak to warm a whole room. Sometimes, people placed a tetsubin ( 鉄瓶 , iron kettle) over the hibachi to boil water for tea . Later, by the 1900s, some cooking was also done over the hibachi . Traditional Japanese houses were well ventilated (or poorly sealed ), so carbon monoxide poisoning or suffocation from carbon dioxide from burning charcoal were of lesser concern. Nevertheless, such risks do exist, and proper handling

The originator of the teppanyaki -style steakhouse is believed to be Shigeji Fujioka of the Japanese restaurant chain Misono. The restaurant claims to be the first to introduce the concept of cooking Western-influenced food on a teppan in Japan, in 1945. They soon found the cuisine
1908-465: The 17th century. A strong disadvantage of this production method is the huge amount of emissions that are harmful to human health and the environment (emissions of unburnt methane). As a result of the partial combustion of wood material, the efficiency of the traditional method is low. The massive production of charcoal (at its height employing hundreds of thousands, mainly in Alpine and neighbouring forests)
1961-587: The Association of American Feed Control Officials banning it in 2012 from use in commercial livestock feeds. Charcoal in the form of charcoal biscuits was consumed in the past for gastric problems. Now it can be consumed in tablet, capsule, or powder form for digestive effects. Research regarding its effectiveness is controversial. Charcoal has been used in combination with saccharin in research to measure mucociliary transport time. Charcoal has also been incorporated into toothpaste formulas; however, there
2014-510: The Industrial Revolution, charcoal was occasionally used as a cooking fuel . It is counted as a smokeless fuel ; that is, the carbon is sufficiently pure that burning it causes substantially less air pollution than burning the original uncarbonized organic material would. In the 20th century, clean-air legislation mandated smokeless fuels (mostly coke or charcoal) in many areas of Europe. In the 21st century, charcoal has been advocated as

Complaints (as early as the Stuart period ) about shortages may stem from over-exploitation or the impossibility of increasing production to match growing demand. In England , many woods were managed as coppices , which were cut and regrown cyclically, so that a steady supply of charcoal was available. But the increasing scarcity of easily harvested wood
2703-492: Was a major factor behind the switch to fossil fuel equivalents, mainly coal and brown coal for industrial use. In Finland and Scandinavia , the charcoal was considered the by-product of wood tar production. The best tar came from pine , thus pinewoods were cut down for tar pyrolysis . The residual charcoal was widely used as substitute for metallurgical coke in blast furnaces for smelting . Tar production led to rapid local deforestation. The end of tar production at
